They know what people buy, but what people buy is what is being currently manufactured. Note 1—The values stated in inch-pound units are to be regarded as the standard. Astj lesson I am learning is that the replacement standard is not a direct substitute for the old standard.

A bars are not widely available. Register now while it’s still free! Would using grade 60 be ok? Test Specimens ; . Producers try to respond to market pressure higher strength, for examplebut there are complications, like ACIwhich limits the use of high strength bars for functional and safety reasons.

Requirements for Deformations 5. Be the first one to write a review. For bending properties test provisions of the nearest smaller nominal diameter deformed bar size shall apply. A number in parentheses indicates the year of last reapproval.

Download Now Defense manufacturing is all about project manufacturing and project accounting. ASTM specs change in response to the supply, not typically because of changes in demand. The nominal perimeter of the bar shall be 3. It’s easy to join and it’s free. The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Asmt you an Engineering professional? Particularly in rail steel, the carbon content is too high for proper welding. Measurements of Deformations 6.


There are no reviews yet. Criminal penalties may apply for noncompliance. A measured length of the bar specimen shall be considered the distance from a point on a deformation to a corresponding point on any other deformation on the same side of the bar. No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of satm bar are measured. When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the producers will change the ASTM.

Many of the laws in this collection were re-keyed into HTML and diagrams redrawn for increased usability and accessibility. Note that many of these documents had to be procured on the used marketplace. To correlate this to our industry, the industry produces a product and contractors buy the product.

This specification has been approved,for use by agencies of the Department of Defense and for listing in the DoD Index of Specifications and Standards. The requirements for degree of bending and sizes of pins are prescribed in Table 3.

In no case shall overweight of any bar be the cause for rejection. Spacing measurements shall not a16 made over a bar area containing bar marking symbols involving letters or numbers.


You are urged to check with the standards organizations or zstm authorities for further information and access to definitive versions of these important laws. Resources Digital Transformation may a166 defined in a number of different ways by analysts or enterprise software vendors. Also, true rail steel bar are not typically fabricated only cut to straight lengthssince asm bars are not as ductile as other types of reinforcing steel. This happens because they have the funding and need to “control” their industry.

ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement

By Authority of the Code of Federal Regulations: The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Red Flag This Post Please let us know here why this post is a661. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

The yield load- shall be recorded when the total gage length under load becomes 1 8. The rebar spec most likely changed when the kinds of retired rail steel and the processing asstm changed. The dynamic of this is that it is the producers who sit on ASTM committees, because those are the people committed to the work.
